Help with removing BB and head set please!
« on: November 24, 2008, 02:11 PM »
I have just stripped my Haro Group 1 RS2 down for sale and need to remove the cups for bottom bracket and headset. Is there a simple way of doing it without damaging anything. Would appreciate any help. Thanks.

everyones gonna tell you not to do this, but this is how i do it, as long as you are fairly gentle :LolLolLolLol:

the right way would be to get a piece of hard wood, and gently tap around in circles until it starts moving.

me...i get a socket set wrench, put the handle end in and do it with that, aint damabged a cup or a bike in 26 years doing it that way

but just dont hit too hard :LolLolLolLol: :idiot2:

Use a hammer and long socket extension bar from a socket set!!

The socket extension is square but rounded at the ends so it doesn't dig into the cups.

Same advice as Mr Magoo!!   He beat me to it!!

Also, if you use this method then hold the socket extension with your fingers inside from the cup you are knocking out to keep it steady & in place. Work your way around the cup, tapping it out evenly to avoid flairing the frame :daumenhoch:

well the way i do it is to get a big flat screwdriver and a rag, then with the rag on the forks to stop the risk of marks i prize the bearing race off the forks a bit at a time  :daumenhoch:

I use the whack technique rather than the prising technique!!

I use the same socket extension bar.

I hold the forks steerer tube with my feet and  bang the crown race off with one hand holding the dropout and the extension bar.

Use rags to avoid any marks!

The other hand is used to whack it with a hammer.  Its easier to get off then to get on.   Tap it all around and it soon comes off.

It would be easier with 3 hands or another person helping but it isn't too hard to do.

Don't forget to wind an old headset nut on top of the forks in case you bugger up the thread.

I use a large shifter, ie adjustable spanner, open it out and tap that with the hamer working round in a circle. Works every time.

Agreed on the "need three people" comment though :2funny:

Nope, not damaged mate.

Thanks for the advice guys, it worked a treat. Gently does it and it eases out after a couple of minutes.

Nice one. :daumenhoch:

As tempting as it was, I don't think it would go down too well with the bloke that's just bought it. Cheers anyway. ;D ;D
